Logic-Based Therapy (LBT) is a proposed modality of philosophical counseling developed by philosopher Elliot D. Cohen beginning in the mid-1980s. It is a philosophical variant of Rational emotive behavior therapy (REBT), which was developed by psychologist Albert Ellis.[1][2][3] However, there have currently been no independent, controlled studies to measure its therapeutic value or advantages over classical REBT.

According to the adherents LBT, people decide to make themselves upset emotionally and behaviorally by deducing self-defeating emotional and behavioral conclusions from irrational premises.[4][5] LBT retains the theoretical base of the cognitive-behavioral psychotherapies, insofar as it contends emotional and behavioral problems to be rooted in malignant and maladaptive thought processes and patterns. LBT considers itself not only a type of philosophical counseling, but a form of cognitive-behavioral therapy. At the same time, LBT remains firmly planted in philosophy by way of the use of formal logic, phenomenological intentionality, and philosophical antidotes in conceptualizing and treating mental disorders and psychosocial difficulties.

In contrast to classical REBT, LBT recasts REBT’s A-B-C-model of psychological disturbance into syllogistic logic.[6] According to classical REBT, there are three psychological points: Point A (Activating event), Point B (Belief system), and Point C (behavioral and emotional Consequence). Ellis argued that the Activating event itself does not cause people to be upset (C); they require also a set of Beliefs that, in conjunction with the event, causes a self-defeating behavioral and emotional Consequence.[7] For example, it is not just having recently been divorced (Point A) that causes a depression (point C), but also the belief that this event is awful and the worst thing that could have happened. Thus, according to Ellis, by finding the particular Activating event and Belief, one can find out what is causing one’s depression (C). Clients can then work on changing their Belief system and their behavior to overcome the depression.

LBT translates the A-B-C-model of psychological disturbance into a form of deductive logic, in particular, syllogistic logic. According to its logic-based approach, the causal model Ellis advanced is not accurate.[8] The depression is not caused by events that occur inside (Point B) and outside (Point A) one’s subjective world. Instead, one decides to feel depressed by deducing a conclusion from a set of premises.[4] For example, you depress yourself by setting up this syllogism:

If I was divorced, then what happened to me is so terrible that I might as well be dead.
I was divorced.
So, what happened to me is so terrible that I might as well be dead.

A syllogism is a deductive form of reasoning having two premises and a conclusion. The idea that the reasoning behind our emotions and behavior can be so ordered in terms of a syllogism was in fact an insight of Aristotle, who called this kind of a syllogism a "practical syllogism." The distinctive feature of this type of deductive reasoning is that the conclusion prescribes something. That is, it evaluates or rates the thing in question instead of merely describing it. For example, in concluding that something is terrible, you are negatively rating it, and therefore will act or tend to act and feel negatively toward it. In fact, Aristotle went so far as to claim that the conclusion of a practical syllogism was always an action.[9]

According to LBT, by syllogizing one’s behavioral and emotional reasoning in terms of the practical syllogism, one is in a better position to find one’s irrational premises, refute them, and replace the unsound reasoning with sound “antidotal” reasoning.[10] For example, the first premise in the above syllogism is irrational because you are exaggerating just how bad the divorce is (thinking of it as though it were on the level of a catastrophic disease or natural disaster).

LBT also accepts the phenomenological thesis that every mental state, including emotions, has a so-called "intentional object" or "object of the mind." That is, there is always an object to which a mental state refers or is about. Thus, if you are depressed, then you are depressed about something. This intentional object is represented in the descriptive minor premise of the emotional reasoning, for example, the premise “I was divorced” in the aforementioned syllogism.[11] In addition, the syllogisms comprising emotional reasoning always rate the emotional object or some aspect of it.[11] For example, in the aforementioned syllogism, you rate your divorce as being “terrible.” This rating element is represented in the consequent (then clause) of the major premise of the syllogism, as in the premise “If I was divorced, then what happened to me is so terrible that I might as well be dead.” Accordingly, the syllogism comprising one’s emotional reasoning can be constructed by first finding the intentional object (O) of one’s emotion; and second, by finding the rating (R) of the emotion. As such, the valid, hypothetical structure of a syllogism comprising one’s emotional reasoning can be symbolized as follows:

If O then R
O
Therefore R

Further, according to LBT, all emotions can be uniquely identified by their specific object (O) and rating (R) elements.[11] For example, the O of anger is always an action; and the rating is a strong negative evaluation of the action itself or the individual performing the action. In depression, the O is an event or state of affairs; and the R is a strong negative rating of the said event or state of affairs, on the basis of which one strongly negatively rates one’s own existence. Thus you may rate the divorce as terrible, on the basis of which you strongly negatively rate your own existence (as in wishing you were dead).

LBT permits clients to trace their inferences to higher order premises that might be at the root of an emotional and behavioral disturbance.[12] For example, by questioning why having been divorced is so bad, another higher level syllogism can be uncovered:

If I was divorced, then that makes me a worthless loser.
If that makes me a worthless loser then what happened to me is so terrible that I might as well be dead.
So, if I was divorced, what happened to me is so terrible that I might as well be dead.

Even higher order premises at the root of the behavioral and emotional disturbance can be uncovered, for example, by asking why being divorced makes you a worthless loser. For example, this higher order syllogism might be uncovered:

I must always be perfect and never fail at anything.
If I must always be perfect and never fail at anything, then if I was divorced, that makes me a worthless loser.
So, if I was a divorced then that makes me a worthless loser.

In this way, the depression can be traced back to a demand for perfection from which a person is deducing their own worthlessness, from which they are in turn deducing the horribleness of what happened.
In contrast to classical REBT, LBT recognizes positive virtues that can be used to guide a person in overcoming his or her irrational beliefs.[13][14] According to LBT, all basic irrational beliefs (“cardinal fallacies”) identified by REBT theorists and philosophers are related to “transcendent virtues” that can overcome them.[15] The following chart displays each such irrational belief and its respective trumping virtue:[14]

Cardinal Fallacy

Transcendent Virtue

Demanding perfection

Metaphysical security (security about reality)

Awfulizing

Courage (in face of evil)

Damnation (of self, others, and the universe)

Respect (for self, others, and the universe)

Jumping on the bandwagon

Authenticity (being your own person)

Can'tstipation

Temperance (self-control)

Dutiful worrying

Moral creativity (in confronting and resolving problems)

Manipulation

Empowerment of others

the world revolves around me

Empathy (connecting with others)

Oversimplifying reality

Good judgment(in making objective, unbiased discernments in practical affairs)

LBT thereby includes a “positive psychology” in addition to the classical REBT emphasis on refuting irrational beliefs. As a philosophical counseling approach, LBT also applies philosophical antidotes derived from the philosophies of antiquity to help clients strive toward their transcendent virtues.[14] For example, the KantianCategorical imperative that says to “treat yourself and others as ends in themselves and not as mere means” can be used as an antidote to damnation of self or others, and thus as a sort of recipe to attaining the transcendent virtue of respect for self and others. Similarly, Nietzsche’s theory about human suffering, which says that suffering can make you stronger and nobler, can be used as an antidote to catastrophic thinking (“Awfulizing”) about personal loss, thereby building courage in confronting the lose and using it to create new positive meanings and values in one’s existence.

LBT also emphasizes willpower in changing and redirecting beliefs and actions.[16] While it makes no commitment to the existence of free will in any metaphysical sense, it recognizes the practical value of building “willpower muscle” as a means to overcoming cognitive dissonance and working towards one’s transcendent virtues. LBT emphasizes and promotes the power one has to change the way in which an event or situation is interpreted by altering one's thought patterns.

While LBT is a form of philosophical counseling, since it addresses client’s emotional problems and provides systematic ways of resolving them it can also be considered a form of psychotherapy. More specifically, because its focus on the client’s cognitions and behaviors in relation to emotional functioning and relationship with REBT it is also a type of cognitive behavior therapy. However, LBT differentiates itself from other forms of cognitive behavior therapy because it does not hold a causative position. That is, emotional responses are not caused by external events mediated through belief systems. Instead, premises about emotions are deduced and inferred from experiences in the world. This position suggests that all emotional responses have a logical structure to them. The fact that emotions contain logical structures which can be subject to investigation and revision was also supported in the late philosopher Robert C. Solomon’s cognitivist theory of emotions.[17]

LBT further differs from other forms of psychotherapy. For example, psychoanalytic or psychodynamic traditions will look for the underline causes of emotional problems. These approaches will explore the client’s early relationships with significant others (e.g., parental figures) and their effect on current relationships and resultant emotional and behavioral disturbances. Interpretation is utilized to provide the client with insights into their psychic organization. In contrast, LBT does not place any particular emphasis on past relationships or the causes of problems and is even less concerned with interpretation. Instead, LBT remains philosophical insofar as it examines reasoning and logical structures created by client. The emphasis is not on the “why” of a problem, but on the “how”; that is, how the person deduces their emotional position and ways in which to alter it for more adaptive thinking and functioning.

LBT’s emphasis on the “willpower muscle” suggests the ability of agency and choice in regard to therapeutic change. Based upon the rejection of causative framework in favor of nondeterministic perspective, LBT maintains compatibility with existentialism and existential psychotherapy. This position of choice is central to Existentialist Jean-Paul Sartre's thought on human freedom and responsibility, which is one of existential psychotherapist Irvin Yalom’s “existential givens”.[18] Here, clients are encouraged to confront their inherent freedom by way of choosing how to interpret situations. As Heidegger suggests,[19] clients can become a “master over moods” by taking responsibility for their moods and emotions and subsequently revising them. Furthermore, this can lead to different ways of thinking about and experiencing the world with the accompanied creation of new meanings in life.

LBT emphasizes the client’s used of deductive logic in their emotional reasoning, which places focus on the cognitive aspect of emotion. As such, it ignores the importance of physiological states and bodily sensations to emotional life, and might be an overly cognitive approach and a way to “control” emotions. Indeed, emotion also consists of physiological components: ultimately there is a causative framework that takes place on a neuronal level. However, LBT contends that it is the entire experience that contributes to the person’s emotional reasoning. This includes the experienced event, any thoughts or beliefs related to the event as well as physiological reactions.

With a LBT counselor’s knowledge of deductive logic, a power differential may be created between the counselor and the client. This could result in the client seeking the “correct” way of deducing premises and develop an overreliance on the LBT counselor. However, the goal is to create more flexible and open ways of interpreting the world and extinguish “absolutist” thinking or unrealistic expectations as a result of a collaborative therapeutic relationship. However, understanding and changing one’s inferences and logical structures requires a certain level of intellectual ability, and consequently, may limit the application.

Although an activating event, such as a divorce or loss of a job, objectively is not on the same level as a catastrophic event, rushing to the conclusion that it is irrational for the client to think that way is potentially invalidating the intensity of the client’s subjective emotional experience. Regardless, empathic understanding and the building of therapeutic rapport is an important component to all psychotherapies and counseling methods and is no less important in LBT.

While LBT may be conceptually sound and have firm theoretical roots, much of psychotherapy and counseling research emphasizes the importance of evidence-based practice, that is, interventions and therapeutic approaches that have scientific evidence for their efficacy.[20] Given this, to establish LBT’s efficacy and effectiveness empirical validation must occur through psychotherapy research methodology if it is to be considered valid by the psychotherapeutic or counseling communities. Although no such evidence is available, anecdotal evidence for LBT’s effectiveness as well as its close relationship with CBT presents it as a possible therapeutic modality.
